ADU rules in Visalia, CA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Visalia Municipal Code Chapter 17.14 (adopted by City Council on January 21, 2025) regulates ADUs ministerially under California Gov. Code 66310-66342, allowing attached or detached units up to 1,200 sq ft and 16 ft tall (18 ft near transit or on multi-family parcels), with 4 ft side and rear setbacks. Owner-occupancy is not required.
Visalia adopted Chapter 17.14 (Accessory Dwelling Unit Ordinance) on January 21, 2025, replacing former Chapter 17.12 Article 2. Per section 17.14.040, ADUs are allowed by-right in Agriculture (A), Open Space (OS), Single-family Residential (R-1-5, R-1-12.5, R-1-20), and Multi-family Residential (R-M-2, R-M-3) zones, as well as in commercial, office, mixed-use, and industrial zones where residential is permitted. Section 17.14.050 requires the City to ministerially approve or deny a Building Permit application within 60 days; staff committed to completing plan checks in 20 calendar days for initial submittals and 10 days for resubmittals. Section 17.14.090 caps detached ADUs at 850 sq ft (under two bedrooms) or 1,200 sq ft (two-plus bedrooms), with a 16-foot height limit, 18 feet near a major transit stop (up to 20 feet to match the primary dwelling roof pitch), and a 4-foot minimum from side and rear lot lines. Section 17.14.080(D) waives owner-occupancy for ADUs. Section 17.14.080(L) exempts ADUs under 750 sq ft from impact fees per state law.
An ADU built without a permit or in violation of Chapter 17.14 is a zoning violation enforceable under the Visalia Municipal Code. Code Enforcement may issue administrative citations, stop-work orders, and require the owner to either bring the unit into compliance or remove it. JADUs additionally require a recorded deed restriction under section 17.14.110(H); failure to comply allows the City to seek injunctive relief or abatement.
